Downgrade teal_data objects in modules for compatibility

Convert teal_data to tdata in teal modules.

Usage

as_tdata(x)

Arguments

x: data object, either tdata or teal_data, the latter possibly in a reactive expression

Value

Object of class tdata.

Details

Recent changes in teal cause modules to fail because modules expect a tdata object to be passed to the data argument but instead they receive a teal_data object, which is additionally wrapped in a reactive expression in the server functions. In order to easily adapt such modules without a proper refactor, use this function to downgrade the data argument.

Examples

td <- teal_data()
td <- within(td, iris <- iris) %>% within(mtcars <- mtcars)
td
#> ✅︎ verified teal_data object
#> <environment: 0x55d0256f89d8> [L]
#> Parent: <environment: devtools_shims>
#> Bindings:
#> • mtcars: <df[,11]> [L]
#> • iris: <df[,5]> [L]
as_tdata(td)
#> $iris
#> reactive({
#>     x[[dataname]]
#> }) 
#> 
#> $mtcars
#> reactive({
#>     x[[dataname]]
#> }) 
#> 
#> attr(,"code")
#> reactive({
#>     teal.code::get_code(x)
#> }) 
#> attr(,"join_keys")
#> An empty join_keys object. 
#> attr(,"class")
#> [1] "tdata" "list" 
as_tdata(reactive(td))

#> }) 
#> attr(,"join_keys")
